Claims.

In the usual arrangementy of an out-swingingv or, Casement type of window, it has always been a matter of particular difficulty to employ window screens, and insofar as these have been possible they have, in the simple hand-operated type of window required the placement of the screen on the inside and the removal of the screeny every time the window was to be opened and closed, or in special instances where window-operating means have been provided, in order to make possible the manipulation of thev window without disturbing the screen, it has involved the placement of operating mechanism on the sillor lower portion of the frame such as to be very much in the way. In accordance with the present invention, a window of easement type may be opened and shut easily, by operating connections permitting a window screen or storm window to remain in position on the inside without dis.- turbance, and the window sill portion is wholly free from obstruction, thereby maintaining usefulness and sightliness of the window sill.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detail certain illustrative embodiments of the invention, these being indicative however, of but a few of the various ways in which'the principle of the invention may be employed.

In said annexed drawing:

Fig. 1 is a perspective view of an embodiment of the invention, taken from the inside; Fig. 2 is a transverse section taken on the plane indi` cated by line Uli-II, Fig. 1; Fig. 3 isa slightly enlarged perspective view showing the sash and detail of the operating mechanism; Fig. 3a is a modified form; Fig. 4 is an enlarged sectional detail taken on a plane substantially indicated by line IV-IV, Fig. 3; Fig. 5'is a sectional detail at right angles to Fig. 4, being taken on a plane substantially indicated by line V-V, Fig. 4.-; Fig` 6 is a sectional detail taken on a plane substantially indicated by line VI-VI, Fig. 3a.; and Figi is a further sectional detail taken at right angles and on a plane substantially indicated by line VII-V11, Fig. 6.

Within a framed opening 2', having' sill 3, easement type panel or sash 4 is mounted by hinges 5 to one side of the frame. Preferably, the hinges, as shown at Fig. 2V lare of an dfisetting form, embodying a hinge member 6 secured to the sash and connected at 1 to the outer covering hinge member 5 which in turn is pivoted at 8. to a frame-engaging plate 9. Ordinarily one hinge at the top and one at the bottom of the sash is. suicient. Desirably, and particularly with larger windows, an abutment plate lll may be provided on the sill 3 for the heel of the sash to ride against'in opening and shutting, and such plate may be slightly concave on its edge Il, and a. wear-shoe l2 may be provided on the sash, such arrangement saving strain on the hinges, particularly in operation in windy Weather. the sill, isA wholly unobtrusive. Secured to the upper portion ofthe sash is an operating arm I4, Fig. 3, to'which is pivoted a link l5, which in turn is pivoted to a connection member I6 projecting from a runner H, the latter being siidable back and forth in -a guide I3, as pulled one way orr another by the pull chains or equivalent cords` I9., 23. The guide I8 which may be of suit'- abl'y heavy sheet metal, may b'e secured to the upper portion of the frame by screwsthrough the screw holes 22., land the chains or cords i9, Zeil, run over pulleys 23. While these latter may be mounted in the ends of the guide i8, it is generally preferable to have them in separate mounting pieces. 2,4, which mate to the ends of the guide I8 and allow some latitude of adjustment in frame-variations. The 'connection member lois preferably provided with an adjustable'take-up, as by 5a tightening screw or bolt 25 through a slotv in the member i6, whereby the length of the connection I5 can be adjusted as required in any condition and be set tight. From the structure so far described, it will be seen that the pullY chains I9 and 2l) control the movement of the runner l1 and the movement of the sash Ll, a pull on one rchain serving toidraw the runner in one direction and through the lever and hinge means |6I5-|4 swing'the window open, and pull on the other chain serving conversely to swing the window shut. As an additional rennement I provide a position-locking means to hold the runner and correspondingly the sash. t in desired position, whether open or shut or at some intermediate position. This in general involves a means on the runner to engage the guide and hold, and such means may be automatically released by the pull chain itself, thereby simplifying the operation and requiring no particular attention. In the runner as shown in Fig. 3 and in further detail in Figs. 4 and 5, this locking means takes the form of expanding wedges 2i', 28, Fig. 5, these riding -against each other by inclined surfacesat 29, and being tensioned toward each other by a spring pull-up 50. The wedge 21 be- The plate I0 being setdown flush into' ing fastened to the runner Il, and the ruimer being of sheet metal and riding within the guide I8 and being of channel-shape, it is seen that the spring 30 tends to wedge the members 2l, 28, forcibly against the bounding-flanges oi the runner I1 and thereby expand it into frictional gripping engagement in the guide I8. When however the pull chain to open the window is drawn upon, it pulls the wedging pair apart and releases the locking action of the runner against the guide. Instead of the wedging action, in some cases I may employ a dog latch, as in Figs. 3a, 6 and 7, wherein the latch or dog-lever is pivoted at 33 to the runner lla, the latch end 34 being projectible through an opening in the runner and into stop-openings 35 in the guide |811. With the latch provided with a slope at one side, it can easily ride along from latch-opening to latch-opening as the runner is pulled in a direction to the left as viewed in Fig. 7, and the spring 36 will hold the latch in engagement. The one pull chain is attached to the runner at a convenient point, and the other is attached to the lever end 38 of the latch. Thus, when the chain at the right in Fig. 'l is pulled, the lever 38 is drawn up into line and the latch 34 is released and continued pull on the chain draws the runner along and correspondingly pulls the window.

The operation of opening and closing the window will be entirely clear from the foregoing, it being seen that in order to close the window, it is merely necessary to pull down on chain handle |971., this releasing the position-lock and pulling the runner and levering the sash into partly or completely closed position, as desired; and conversely by pulling down on handle 2th, the sash is opened. :The sill 3 is unobstructed. Particularly conveniently also, a window screen or an inner storm Window S can be placed in position against the inner stops 39 and remain there undisturbed while permitting any desired manipulation of the window beyond. With particular advantage, the guide I8 conjointly includes a screen or storm sash engaging means, as a downwardlydirected iiange 4B, Figs. 1, 4 and 6, to engage in a groove in the screen or storm sash, Fig. 4.
